Cardiff University's Residences Services have previously procured the services of Contract Cleaning companies to support with the cleaning of Residences buildings at the end of the academic year, during conference / event period and at the start of the new academic year. The cleaning requirements are particularly challenging due to the environment and often have short turnaround times. We anticipate creating an open framework for this requirement that includes several suppliers to mitigate this risk of service delivery failure and to ensure there are sufficient contractors available to undertake all required works.
